The film is a drama set in Spain where a small group of American young adults is living. The leader of the group is a drug dealer. The others are there living carefree lives as beatniks. The leader has more nefarious aims in mind, and uses drugs to lure the others into lives of crime. Most of the film is in black and white, but there is a psychedelic sequence depicting the purported effects of the group using LSD which was filmed in color.
